A simple pendulum consists of a 4.9-kg mass attached to a string. The pendulum is pulled to the right and held at rest so that i

t is 2.08 m above the lowest point in its swing. If you let it go from this point, how fast (in m/s) is it traveling at the lowest point of its swing (on the initial pass)

Answer:

6.384 m/sec^{2}

Explanation:

The velocity is given by;

We know;

PE= mgh

KE= 1/2 mV^{2}

but KE=PE

==> 1/2 mV^{2} =mgh

==> 1/2 V^{2} =gh

==> v=\sqrt{2gh}

puting g=9.8 m/sec2

h=2.08 m

==> v= 6.384 m/sec^{2}=

Which is not a benefit of a sporting organization? a. To control all of the people in the community b. Bringing people together
Anit [1.1K]

Answer: a. To control all of the people in the community

Explanation:

The sport organization help in bring people of different communities together. It removes any kind of discrimination based on caste, gender, race, and others. People are united in a single team to bring about unity in them. The sport organization does not control the people in the community instead can bring change in their thinking and opinion about people of the other community. The sports activities are recreational in nature, they build social interaction between people of different communities, control good health, make communities safer.

Define thermopile and peltiers??​
NikAS [45]

Answer:

Thermopile is an electronic device that converts thermal energy into electrical energy.

A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.

An electron is ejected from the cathode by a photon with an energy slightly greater than the work function of the cathode. How w
Ksivusya [100]

It will be approximately equal.

<h3>How will the final kinetic energy change?</h3>

We can infer that all of the energy in the electron is Potential energy (PE) because the energy provided by the photon is hardly enough to outweigh the work function.

It will gain kinetic energy (KE) as it advances in the direction of the anode because it is moving through an electric field. All of the PE will have been transformed to KE by the time it reaches the anode.

According to the question

K = hf - W

W = Work function

The energy of photons is comparable. After conversion, there was only a little amount of KE remaining.

Therefore, PE (W) essentially equals KE (K).

It will about be equal.

A hot air balloon has a mass of 300 k gincluding the basket. The hot air inside the balloon weighs 17,000 N. Determine the maxim
padilas [110]

Answer:

500 kg

Explanation:

If 17000 N hot air weight displaces 25000 N cold air weight, then the difference of 25000 - 17000 = 8000 N in weight would result in the buoyant force that lift the whole system.

If g = 10m/s2 then the total mass that it can lift (including the 300kg basket) is

8000 / 10 = 800 kg

So the maximum additional load that the balloon is able to lift is

800 - 300 = 500 kg
